Scope of This Document This standard details definitions@ method of measurements and minimum performance characteristics for Forward Link Only devices. This standard shares the purpose of [1] by ensuring that a Forward Link Only device can obtain service in any system that meets the compatibility requirements of [1]. Revision A of this specification includes performance requirements for Forward Link Only 8devices supporting 6 and 8-MHz wide channels across the entire UHF band. Revision A includes the: ? Addition of three distinct sub-bands to cover the entire UHF band. Sub-bands 0@ 1 and 2 cover the lower@ middle and upper part of the UHF band. The sub-bands allow for focused testing of the particular band segment of interest for a given device. ? Addition of recommended sub-band number for each test. ? Specification of the recommended channel number used for executing tests in different sub-bands. ? Addition of test procedures and performance requirements for 8 MHz wide channel in sub-bands 0@ 1 and 2. ? Addition of test procedures and performance requirements for 6 MHz wide channel in sub-band 0 and 2. ? Elimination of redundant test points to speed up the tests without compromising the test functionality. ? Addition of a new channel profile 8 to characterize device performance in a long delay channel. ? Addition of a new MAC layer test to characterize demodulation performance for transmit mode 2 with (16@ 14@ 2) outer Reed Solomon (RS) code. ? Revision of all channel profiles to support both 6 and 8 MHz channel bandwidths. ? Addition of a new co-channel single tone interference test for 6 and 8 MHz channel bandwidths to emulate the effects of a narrowband interferer. Compatibility@ as used in the connection with this standard and [1]@ is understood to mean that any Forward Link Only device can receive multicast service in a Forward Link Only network. Test methods are recommended in this document; however@ methods other than those recommended may suffice for the same purpose. All the performance metrics in this standard are meant for non-receive diversity Forward Link Only devices i.e. for devices with one receive antenna. For testing of Forward Link Only devices with receive diversity i.e. with more than one receive antenna@ the 1 Forward 2 Link Only device shall be configured so that just one receive chain is used for 3 demodulation.
